PRIMER.

Application filed February 2S, 1927.

This invention has reference to a primer designed for use in connection with intake manifolds of internal combustion engines and aims to provide novel means whereby a quantity of gasoline may be sprayed into the intake manifold at a point between the carburetor and cylinders of the engine.

Another important object of the invention is to provide a device of this character o whereby an engine may be primed by an auxiliary primer independently of the carburetor, thereby eliminating the possibility of flooding the carburetor.

A still further object of the invention is 5 to provide. a primer of this character wherein the operating lever will automatically return to its inoperative position after the priming charge has been ejected therefrom. lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood 0 Figure 1 is an elevational view illustrating a device constructed in accordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is a vertical sectional view through a primer constructed in accordance with the invention. Y

Figure 4 is a sectional view taken at right angles to Figure 3.

Figure 5 is a sectional view through the nozzle of the primer.

Referring tothe drawing in detail, the device includes a tank 5, the bottom 6 there of being curved as clearly shown by the drawings and provided with an opening normally closed by the cap 7, so that the contents of the tank may be drained at the will of the operator.

The upper end of the tank 5 is bulged as at 7 so that when the upper end is flexed, such action will result in compressing air in the tank 5 to force liquid therefrom. Secured to the end wall 7 and arranged substantially centrally thereof is an upstanding pin 8 to be engaged by the finger 9 that eX- tends laterally from the valve operating rod Serial No. 171,670.

10, which valve operating rod carries the valve 11 at its forward end, which valve operates in the valve casing 12 that is disposed in the pipe line 13 that includes pipe 14.

This pipe 14 communicates with the tank 5 at a. point adjacent to the bottom thereof and hasits upper end closed by means of the cap 15 so that gasoline may be poured into the tank 5 through the pipe 14 to fill he tank 5 or replenish the supply of gasoine.

Connected with the valve casing 12 is a pipe 16 that is provided with a threaded portion 17 to be positioned in a threaded .f

opening formed in the intake manifold of an internal combustion engine at a point between the carburetor and cylinders of the engine, there being provided a lock nut 18 which may be moved into frictional engagement with the intake manifold to lock the device in position.

At the outer end of pipe 16 is a nozzle 19 that has its outer end closed and provided with a plurality of openings 20 throughs,-

which the gasoline may pass on its entrance to the intake manifold, the gasoline being delivered to the intake manifold, in a line spray.

Secured to the tank 5 and extending above the upper end of the tank, is a supporting member 21 which is provided with openings to receive the pipes 13 and 16 to hold the pipes against movement when the operating rod is moved to accomplish the purpose of e.

the invention.

The reference character 22 indicates a pipe that extends into the tank 5 at apoint adjacent to the upper end thereof, which pipe has an upwardly extended port-ion 23 closed by means of the top 24 which pipe affords means whereby the air may be released from the tank 5 when the tank is being filled with gasoline.

In order that the operating rod 10 will be returned to its initial position after it has been operated, a coiled spring 25 is provided, the same being connected with the rod at one of its ends, the opposite end thereof being anchored to the dashboard of the motor vehicle, through which the rod passes. Thus it will be seen that as the rod 10 is rotated in one direction to operate the primer, the spring 25 will be placed under tension to return the rod to its initial position as soon as the rod has been released by the operator.

From the foregoing it will be obvious that due to this construction, a priming charge may-be delivered to the intake manifold of an internal combustion engine at a point be-l tween the carburetor and cylinders, thereby eliminating the necessity of priming the engine through the carburetor which often results in flooding of the carburetor to such an extent that the engine will not lire until the Carburetor has been drained or the excessive gasoline removed.

I claim l. A primer for internal combustion engines including a tank, a pipe communicating with the interior of the tank, a pipe carrying a nozzle, and in communication with the lirst mentioned pipe, the last mentioned pipe being disposed' in an intake manifold of an engine, and said tank having a bulged flexible end ivall adapted to be flexed to compress air in the tank to force a quantity of liquid through the pipes.

2. A; primer for internal combustion engines including a tank, a. pipe in communication with the tank, a pipe communicating With the first mentioned pipe and including a nozzle adapted to be positioned Within an intake manifold, a valve for controlling the passage of liquid through the pipe, means for operating the valve, and means for simultaneously compressing air in the tank to force liquid through the pipes.

3. A primer for internal combustion engines including a tank, said tank having a bulged iieXible end Wall, a pin disposed centrally of' the iiexible end Wall, a pipe communicating With the tank, a pipe communicating With the first mentioned pipe and having a nozzle disposed Within an intake mani- ..t

fold, av valve in the last mentioned pipe for controlling the passage ofliquid through the pipes, a rod for operating the valve, a finger extending from the rod and adapted to engage the pin to flex the end Wall and compress air in the tank to force Vliquid from the tank, andV means for returning the rod to its initial position.

4. A primer for internal combustion engines including a. tank having a flexible end :a

Wall, a pipe for establishing communication between the tank andintake manifold Vof an internal combustion engine, means for controlling the passage of liquid through the pipe, and means Vfor simultaneouslyV flexing PATRICK J. REGAN.
